Java Command Not Found on Linux

Java command not found on Linux

You can add one of the Java path to PATH variable using the following command.

export PATH=$PATH:/usr/java/jre1.6.0_24/bin/

You can add this line to .bashrc file in your home directory. Adding this to .bashrc will ensure everytime you open bash it will be PATH variable is updated.

java -version resullts -bash: java: command not found (in linux)

You should have your java installation directory added to PATH environment variable in order to use java from terminal. For example:

export PATH=<your java Directory>/bin:$PATH

java command not found on remote machines linux

"command not found" error means that particular command you're trying to invoke is not found in neither of directories listed in $PATH system variable.

There are two ways how to fix this:

1) Specify full path when running an executable:

/opt/jdk-12345/bin/java -version

2) add the very same path to the beginning of PATH (change will be applied to current session only):

export PATH=/opt/jdk-12345/bin:$PATH
java -version

To fix this permanently, add that line (export PATH=/opt/jdk-12345/bin:$PATH) to ~/.bashrc (if BASH is default shell for that user) or to ~/.profile

Also because this is Unix Java, make sure to set up LD_LIBRARY_PATH and CLASSPATH variables if you're running some server applications. Usually this is done in application startup scripts, no need to go global.

Please verify which Server OS you're running ( uname -a or /bin/uname -a ) because different Unix systems have different package managers: apt-get is for Ubuntu/Debian, rpm for RedHat, Entropy for Sabayon/Gentoo, etc...

Multiple Java installations leading to 'Command not found' error on Linux 2.6 system

Turns out my Java was installed at a different location completely and that wasn't included in the path. This tutorial(https://www.tecmint.com/install-apache-tomcat-in-centos) explains everything in detail except it missed out the point to add Java to the path.

Added that to the path and it's working perfectly since then. Thanks for your help guys :)

JAVA command shows nothing in a command prompt

I have seen this occasionally on Windows, and uninstalling all Java distributions (those with an installer) and reinstalling the one you need usually fixes it for me.

If you do a lot of Java development you may need to have several versions of Java available on your system to be sure that everything is compatible for a given project. In that case, ZIP distributions that just need to be unpacked and not installed are very handy, especially with a good IDE that just needs to be told where to find them.

Ubuntu Java Application Not finding the command javac when java 11 is confirmed installed

You have installed the Java Runtime Environment (JRE): openjdk-11-jre which allows you to run java software.

And should install the Java Developer Kit (JDK) in order to compile code:

sudo apt install openjdk-11-jdk
